I'm a husky, tall guy, but i'm a B... the 42 looked alright on my wrist and I actually thought the 38 looked good too. I have a square watch thats similar in size to the 42 and it does look a little big on my wrist, and I also have 38mm watches that looks good on my wrist. I believe Ic an truly pull off both... I preordered a 38 and hopefully it'll be here on friday!! I'm thinking of just trying it out and if I don't really like it then i'll go to a 42, but I think the 38 will be fine.
